What happens if I subscribe to a podcast on my iPhone?

If you go into your Podcasts app on your iPhone or iPad and take a look at a title, you'll see an option to "Subscribe." If you subscribe, that simply means that the most recent episode will be downloaded into your "My Podcasts" section. While you are subscribed, new episodes will download to "My Podcasts" automatically as soon as they are available. If you don't want to subscribe you can always download individual podcasts by tapping the download icon (the cloud with a down arrow). You can also stream podcasts simply by tapping on the title, but this will require a continuous internet connection, whereas downloaded podcasts can be played offline. To unsubscribe just tap "Unsubscribe," which appears in the same position as the "Subscribe" button once you are subscribed.
